Friends Til The End~Shannen Doherty (Dvd 1997) ~ ULTRA RARE

Heather Romley (Shannen Doherty) and Suzanne Boxer (Jennifer Blanc) are both singers who have been competing against each other as long as they can remember. Usually, however, the more talented Heather won all the competitions, which resulted in Suzanne being insecure, going insane, and carrying a grudge against Heather, while being pushed by her stage mother.
Years later, Heather enrolls in college, Simon (Jason London). Suzanne, now using the alias of Zanne Armstrong, also enrolls in the same university, with the intention of destroying Heather's life. In the course of this insane evil revenge scheme, she becomes apparent best friends with Heather. But meanwhile, she is evilly destroying all Heather's friendships, and she even successfully seduces Simon himself. Heather is now being threatened with expulsion from college for plagiarism and is kicked out of her own band, with Zanne taking her place. Heather wants to take down Zanne, and sets out, to prove her real identity.
